2 Claims.

The object of the present invention is to provide a novel form of casement window which shall include means permitting raising and lowering of a lower and an upper sash in the ordinary manner and the pivotal inward movement of each sash member so that the same may be projected into a room for cleaning the exterior surface of the glass.

The specific object of the invention is to provide a casement window of the said type which will be weatherproof and sturdy in construction, and, at the same time, of relatively simple and inexpensive construction.

Further objects of the invention will be set forth in the accompanying specification with reference to the drawings, in which:

Figure 1 is a view in elevation, partly broken away, showing an embodiment of the invention in position, the view being taken from the inside of a room.

Figure 2 is a sectional elevation of the construction shown in Figure 1, the section being taken on the line 2-2, Figure 3.

Figure 3 is a horizontal section on the line 3-3, Figure 2.

Figure 4 is a lower end, and therefore, fragmentary portion of. the embodiment shown in Figure 2, with both sash members projected inwardly.

Figure 5 is an enlarged perspective View, partly broken away and partly in section, showing one of the two sash member and its accompanying slide and connections with the latter.

Figure 6 is an upper corner View of a lower sash member, in perspective, showing the slide latch pressed back out of active position, through the pressure of the sash.

Figure 7 is a detailed View of the slide latch in active position.

Referring to the drawings, the casement frame comprises a lower member I and an upper member 2 connected by the side members 3. Each side member at its inner base is cut away to form an area having a back vertical wall at 3x to afford the rear face of a slideway for a slide generally indicated at 4.

The front vertical abutment of the slideway, in each case, comprises an applied vertical strip 5. The slide 4 operates in connection with the lower sash 6, the upper sash being indicated at 1.

To provide slideways for the slides operating with the upper sash 1, each side casing member 3 is vertically grooved to receive an abutment strip 8 rabbeted into the groove, its abutment strip 8, in each case, guiding the front face of one of the two rear slides 43?.

Each one of the four slides is of the same construction, and a detailed view thereof will be seen in Figure 5. The slide is U-shaped in cross sec- 5 tion and stamped or rolled out of sheet metal. At its base, and, for example, at the point p, it may be pivoted to the appropriate sash. In the present instance, each slide member is directly pivoted to a bar 9 having an aperture at its 10 upper end so that it may receive a screw to enter the screw opening at s, the bar being further held against lateral movement by its placement between the lateral fiange at the front face of the sash and a short strip 9m.

Above bar 9, each slide is formed with a relatively long slot at ill to receive a slide stud H carried by a link I2 which, at its lower end, is pivoted to the sash. A washer Ila: may be interposed betwen the stud and the slide. The slide 0 above slot I8 is formed with a second vertical slot at 13 to receive a slide stud [4 of a latch arm 15 having at its lower end a pin l6 adapted to enter a latch-receiving recess at I! formed in the edge of the sash. Near its upper end, the 25 vertical side member of each sash is formed with a longitudinally extending aperture which receives a detent pin l8 carrying at its inner end of the sash an operating finger piece [8.10, the adjacent slide being formed with an aperture 30 at 19 to receive the detent pin.

It will be understood that each sash may be raised and lowered exactly in the manner of the standard sliding window construction, and that during such movements the two slides associ- 35 ated with each sash will be vertcially raised and lowered with the respective sash. Each sash may be weighted and to that end each slide may carry a hook device at 20 to receive the appropriate one of the four Weight-carrying chains generally in- 40 dicated by the numeral 2|, these chains carrying weights 22 and each chain connected to a hook 20 extending upwardly and thence over an appropriate guide roller, the guide rollers being generally indicated at 23.

When each of the lower two slides is in lowermost position as shown in Figure 1, there is carried above the said slide a spring catch which is shown in its two positions in Figures 6 and 7 respectively, the catch being indicated at 24 and having an angularly bent catch arm at 24m. The spring catch is carried by abutment strip 8, in each case, being countersunk flush with its inner face, shown more particularly in Figure '7.

When the lower sash is in closed position, as

shown in Figures 1 and 6, its rear face will have moved the spring catch so that angularly bent catch arms 24a: lie rearwardly of the lower slides 4 and hence out of latching position relatively to said lower slides 4. The lower slides, therefore, may freely reciprocate vertically with the lower sash. However, when the lower sash is moved outwardly for ventilation or cleaning, the spring catch member 24 will be released and catch arms 24a: will move directly over the lower slides t and will prevent derangement of the elements through an inadvertent attempt to raise the lower sash while it is swung inwardly.

When the elements of the casement window are in the position of Figure 1 and it is desired to ventilate the room, the detent pins l8 are withdrawn by movement of the finger pieces I83: toward each other and the sash may be pulled inwardly, pivoting at the point p on the two lower slides 4, the movement continuing until stopped by latch arms l5, whereupon the lower sash will lie in the position shown in Figure 2 or in an intermediate position determined by a plurality of detent recesses into which stud i l and latch arm l5 may be positioned.

Should it be desired to move the lower sash inwardly for cleaning, it is only necessary to spring the inner ends on latch arms I 5 in an outward direction so that the studs HS will be with drawn from the apertures l7 formed in the sash and the sash may then be moved down to the position shown in Figure 4. The upper sash may then be brought down and by corresponding release, first of the detent pins I8, and, secondly, by release of the latch arms l5, may be swung inwardly to the position of Figure 4 for cleaning or maximum ventilation of the room.

It will be noted that the casement is of unique construction in that the supporting faces for the two sash members are so designed as to permit the member, when in lowermost position, to

swing inwardly until it lies down upon the rear face of the normally lower sash.

To aid in the weatherproof construction of the casing, the lower frame member I thereof may be formed with a tenon at la: and the lower horizontal member of the lower sash may be grooved to receive the tenon or rib and the outer wall of the groove may comprise a strip of metal as, for example, brass or coper 6m: (Figures 2 and 3) which will be slightly flared at its base to permit the movement of the lower sash to ventilating position, as shown in Figure 2, and, at the same time, maintain a water-tight seal at the base of the sash.

Having described my invention, what I claim and desire to secure by Letters Patent, is as follows:

1. In a casement window comprising upper and lower vertically movable sash members, of a casing for said sash members, a pair of slides disposed at the sides of each sash, meansv carried by the casing to limit said slides to vertical movement, means intermediate each sash and its slides for latching the same together and providing for release of said latching means, link connections between each sash and its slide members, permitting a pivotal movement of the sash away from the casing for projection into a room, and means carried by the casing and acting automatically to latch the slides appropriate to the lower sash when said sash is pivotally swung relatively to the casing, whereby the said slides are restrained against vertical movement.

2. In a casement window, a sash frame having vertical slideways, longitudinally slotted slides therein, a sash linked to said slides by three links on each side, one constituting a latching link engaged in a slot of the slide, an intermediate link engaged in another slot of the slide, andthe third a rocking link pivoted at the lower end of the slide. 7
